• Git-based workflows: branching strategies, PR culture, code review

Testing (Emphasized)

• Strong experience with unit, integration and end-to-end testing
• Hands-on experience with tools such as xUnit or NUnit and mocking libraries
• Experience with integration testing approaches such as TestServer or similar

• Understanding of AI-driven workflows and agent-based systems

• Ability to evaluate AI outputs and design reliable user-facing features
• Awareness of data privacy and security considerations when working with AI

Nice to Have

• Azure AI services and monitoring tools
• CI/CD pipeline experience
• Experience in healthcare or regulated environments

Who You Are

• You write clean and maintainable code
• You take ownership and deliver end-to-end

If you enjoy building real products and working with modern technologies, we would be happy to hear from you.
